Answer:
The distance by which the spring stretches is 1.48 cm.
Explanation:
Given that,
An object on a vertical spring oscillates up and down in simple harmonic motion with an angular frequency of 25.7 rad/s, 
We know that angular frequency in SHM is given by :
When the object is allowed to hang stationary from it, the force due to spring is balanced by its weight. Such that :
From equation (1) :
So, the distance by which the spring stretches is 1.48 cm.
Answer:
The angle that will have the most range (Goes further) <u>will be the one that is shot with 60 ° with the horizontal. </u>
Since the one that shoots with respect to the vertical, it will only reach higher. And it won't go as far as the horizontal.
